You can calculated reduced volume by getting the starting volume and subtracting it from the finished volume For example, If I had 890ml of water and I had 155ml left, How much has the volume reduced by. 890 - 155 = 735. So the answer would be that the water has been reduced by a total of 735ml.
If the direction of motion is constant then the velocity is the same as the speed in that direction. If the direction is not constant, the information given is nowhere near sufficient to calculate the velocity.
You add all the forces. Not quite sure what you mean with "no x value is given", but if you don't know ANYTHING about the forces, then you can't calculate the net force either.
Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.
0.2*50=10 50+10=60 :)
It reduced their dependence on the direction of the wind.
If two or more forces act on the same object, and in the same direction, you can calculate the net force by simply adding them.
YES!

Usually you would multiply the two numbers together unless they could be reduced. If they could be reduced you would reduce them and then multiply them by each other.

No. A wave travelling in the opposite direction would have its amplitude increased.
The substance that is reduced in a lead battery as it generates electric currents is lead dioxide. You can recharge the battery by reversing the direction the current is flowing.
Speed (in the radial direction) = slope of the graph.
Work = Force x Displacement in the direction of the Force.
By adding the two velocities.
If they're exactly in the same direction, then the resultant is also in the same direction, and its magnitude is equal to the sum of the two individual magnitudes.
